(16) User ROM Blank Check
The boot program will check to see if the whole user ROM area is blank and return the result in
response to the user ROM blank check.
• Command, H'4D, (1 byte): Blank check for user ROM
• Response, H'06, (1 byte): Response to the user ROM blank check
• Error response, H'CD, (1 byte): Error response to blank check for user ROM
• Error code, H'52, (1 byte): Erasure incomplete error
(17) Data Flash Blank Check
The boot program will check to see if the whole data flash area is blank and return the result in
response to the data flash blank check.
• Command, H'62, (1 byte): Blank check for data flash
